The Viabono Hostels need to fulfil strict requirements. High standards for customer value and environment compatibility are applied, characterising these Hostels and ensuring a high quality of "natural travel and enjoyment". The list of criteria includes the conservation of resources in terms of waste, energy, water and climate as well as the protection of nature and the countryside. Moreover, a comprehensive concept, loosely based on the I FEEL GOOD Profile, offers a health and wellness program for young people in terms of nutrition, activity and relaxation. Information and management and educational aspects round off the Viabono Profile. Personally experiencing a sustainable lifeworld and its real life conditions are an important prerequisite for the success of the educational program.
